Embodiment 1

[0057] Embodiment 1: VNF network element accesses CE equipment

[0058] Taking VNF 1 as an example, assume that the service VLAN tag corresponding to VNF 1 is VLAN101.

[0059] VNF network element 1 sends a service message carrying VLAN101 to OVS (Open Virtual Switch, open source virtual switch) device 1, and the destination MAC address of the service message is the MAC address of the EOR device (assumed to be 1-1-1).

[0060] OVS device 1 receives the service message sent by VNF network element 1, adds the VLANTag in the host (assumed to be VLAN 201) for the service message, generates a service message in QinQ (double-layer VLAN) format, and sends it to TOR device1.

[0061] When TOR device 1 receives the service message in QinQ format, it performs VLAN→VXLAN mapping according to the outer VLAN Tag (VLAN 201) (assuming that the mapped VXLAN ID is VXLAN 1), and performs VXLAN encapsulation on the service message to obtain VXLAN-encapsulated service packets (also called QinVX...

Embodiment 2

[0065] Embodiment 2: Mutual access of VNF network elements

[0066] Taking VNF 1 accessing VNF 3 as an example, assume that the service VLAN tag corresponding to VNF 1 is VLAN 101, and the service VLAN tag corresponding to VNF 3 is VLAN 103.

[0067] VNF network element 1 sends a service message carrying VLAN101 to OVS (Open Virtual Switch, open source virtual switch) device 1, and the destination MAC address of the service message is the MAC address of the EOR device (assumed to be 1-1-1).

[0068] OVS device 1 receives the service message sent by VNF network element 1, adds the VLANTag in the host (assumed to be VLAN 201) for the service message, generates a service message in QinQ (double-layer VLAN) format, and sends it to TOR device1.

[0069]When TOR device 1 receives the service message in QinQ format, it performs VLAN→VXLAN mapping according to the outer VLAN Tag (VLAN 201) (assuming that the mapped VXLAN ID is VXLAN 1), and performs VXLAN encapsulation on the service...

Abstract

The present invention provides a message forwarding method and device. The method includes: receiving a VXLAN-encapsulated service message sent by a TOR device; releasing the VXLAN encapsulation, and determining that the destination MAC address of the service message is the EOR MAC address of the device, determine the first VPN corresponding to the first service VLAN Tag according to the first service VLAN Tag carried in the service message; according to the destination IP address of the service message in the first Search for layer-3 forwarding entries in the VPN, and perform layer-3 forwarding for the service packets according to the search results. By applying the embodiments of the present invention, the capabilities of the EOR equipment can be fully utilized, the functional complexity of the CE equipment can be reduced, and network resources can be saved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message forwarding method and device. Background technique [0002] In a communication cloud network, a VNF (Virtualized Network Function, virtualized network function module) network element, as a network device carried on a virtualization technology, provides network service functions. In a non-SDN (Software Defined Network, software-defined network) network environment, network forwarding services are provided for business communications between VNF network elements, and between VNF network elements and CE (CustomerEdge, user network edge) devices. VNF network elements are connected to TOR (Top of Rack, rack switch) equipment, and TOR equipment is connected to EOR (End of Row, cabinet switch) equipment as underlay (lower layer) equipment to provide between VNF network elements, VNF network elements and CE equipment Layer 2 channel function between them. Usual...
